“…Among the series of catalysts for the elimination of volatile organic chemicals, noble metal-supported catalysts have received tremendous attention because of their excellent catalytic activities and high reaction rates in methane combustion, ,, especially for Pd-based catalysts. ,,, Although noble metal-supported catalysts have high efficiencies, their high price, low availability, and easy sintering at high temperatures limit their large-scale industrial applications. ,, Therefore, transition metal oxide catalysts are fast becoming the focus of researchers due to their lower cost and comparable catalytic activity to noble metal catalysts. In the reaction course of methane catalytic combustion, the activation of the C–H bond is a key step, and NiO is considered to be one of the potential transition metal oxide nanoparticles capable of replacing noble metal catalysts due to its excellent performance in the activation of C–H bonds. ,,,, Consequently, interest in the fabrication of various NiO nanomaterials as high-efficiency and low-cost catalysts in lean methane catalytic combustion has been growing. , …”

“…For purified MoO 3 catalyst, the reduction peak appears only at 657 °C, which correspond to the reduction of Mo 6+ to Mo 5+ and Mo 4+ . 51,53,54 After Cu had supported on the carrier, the reduction temperature drops sharply. Simultaneously, a distinct shoulder peak at 492 °C also appears, which can be viewed as the reduction of Mo 6+ in CuMoO 4 .…”

“…Teniendo en cuenta lo anterior, a continuación, se presentan los resultados de la actividad catalítica de catalizadores monometálicos de hierro y molibdeno y materiales bimetálicos de hierro-molibdeno y hierrovanadio en la reacción de oxidación selectiva de metano y metanol. Todos los materiales fueron preparados por el método sol-gel y calcinados a 750 °C, la descripción detallada del proceso de síntesis se encuentra en publicaciones previas [31], [48].…”
